meqhlh a As ,4 indicated in 'Fig. l each end of the sha t 4 isrece ssedat .5 to receive a coiled springfi. ho

7 turns.

One end of each spring 6 is seated in an opening in a block 7 that issecured with a drive fit in the bottom of its recess 5. In this mannereach spring 6 is fastened at one end to the shaft 4 and tends to turnit, whereas the other end of each spring, is anchored by passing into alongitudinal slot 8 in a fixedly held headed pivot pin 9. Each pivot pinpasses through a bearing opening in a bracket 10 or 10" and is receivedin the associated recess 5 in one end of the shaft to provide a pivotalsupport on which the shaft Each pivot pin 9 is secured in place by aheaded screw 11 that is, received in a tapped opening in the associatedsupporting .bracket 10 or 10 and the head of screw 11 overlaps the" headof the companion pivot pin 9 and secures the latter firmly connected tothe associated" jection on the right-hand supporting bracket 10 andextends into the path of the right-hand pocket or carrier 2 and limitsthe forward movementthereof and of the shield.

The supporting brackets by which the shield is attached to the machinemay be of any suitable construction depending somewhat on the particularmachine to which the shield is 'to be attached.

In the Figs. 1 to 5 construction each of the supporting brackets 10, 10is provided with a foot piece 15 that is pierced to receive the stem ofa headed screw 16, which is one of the usual screws employed in theRemington standard machines" to secure parts to the front cross bar 17of the carriage 18. The screws 16 usually employed for other purposesare also made available in the present instance to secure the supportingbrackets 10 and '10 to the carriage. The

hole in the'foot piece 15. in the right-hand bracket 10 is elongated, asshown in Fig. 3, to

provide a slight relative adjustment between the brackets in order thatthe shields may be readily placed on different machines having thescrews 16 in slightly different positions thereon. I also prefer tosecure the right-hand supporting bracket 10* in place with the aid of aclamping 'plate 18 interposed between the head of the associated screw16 and foot piece of the bracket, .to provide a securehold on thebracket and preventthe slotted foot piece from spreading. In theconstruction shown in Figs. 6 to 9 inclusive the shield 1 is made oftransparent celluloid, mica, or similar material tinted as previouslydescribed. The frame by which the shield is supported in this form ofthe construction includes an inverted U-shaped sheet metal frame thatembraces the shield on three of its edges and is riveted at 19 to theintervening shield. A tubular sheet metal member i -constitutes a rock.shaft by which the shield is supportedfor pivotal movementas previouslydescribed. This tubular member 4 has upwardthereof which embrace theshield 1 on opposite the erasure has been made.

sides thereof and are riveted thereto and to each other at 21.

The shield supporting frame comprising the tubular member 4 20 and 2 ispivoted to supporting brackets 22 substantially as hereinbeforedescribedin connection with the form of construction shown in Figs. 1 to5 inclusive. Thus, each'headed pivot pin 23 receives a bearing in theassociated supporting bracket 24. and is received in one end of thetubularmember 4 and is held in place by a clamping screw 25 threadedinto the companion supporting bracket. Each pivot, pin 23 is grooved at26 to receive and provide an anchorage'for the companion coiled spring27 at 'one end thereof, the other end of each spring beingjconnected toa block 28 held by a drive fit in the tubular member 4 Each bracket 24has an upwardly directed extension 29 that constitutes a stop with whicha side arm of the member 2 of the shield-carrying-frame coacts to limitthe forward movement of the frame under the action of the springsZ'l.

It will be seen that the supporting brackets 24 in this formofconstruction are of different formation from the brackets 10 and 10previously described due to the fact that thebrackets 24 are intendedfor attachment to'the usual arms 30 of the carriage of a No. 6 Remingtonnoiseless machine. At its attaching end 2% each bracket 24 is madesubstantially u-shaped in cross section. This enables each bracket toembrace the edges or" the companion arm 30 of the carriage and tobefixedly secured thereto by a companion pivot screw 31 usually employedfor mounting the paper bail, a nut 32 coacting with each screw 31 tohold the companion bracket in place. r

It will be understood that in'each of the constructions described, theshield and its su'pporting brackets may be readily attached as a unit toa typewriting machine by means existing in the machine and withoutmodifying. the

structural features thereof. I

One of-the main objects of mounting each of t the shields so that it maybe readily moved'to an ineffective position, and-in providing spring.means to enable the shield to be automatically restored to effectiveposition when, released, is to facilitate making erasures at or nearthefront and topof the platen while thework sheet or sheets remain in themachine. In reaching back .to make an erasure the operators arms comeinto contact with the shield and move it down to an unobstructingposition where it gives free access to the work sheet. While making,'such1'30 erasure the operators arms remain on the shield and hold itdown. When the erasure is made the spring for the shield return it tonormal "effective position when the operators arms are readily appliedas an attachment to typewriting' 'irio V and like machines, and one thatis'automatically position in the act of making erasures and isautomatically returned to effective position after 1'45 Variouschangesmay be made in the construction, and features thereof may be employed,Without others, without departing from, my invention as it is definedin, the'accompanying. claims, 1

What I claim as new and desire to secure by Letters Patent is:

1. In a typewriting or like machine, the combination of a platen thattravels in the direction of its length, a tinted transparent shieldthrough which the operator may view the writing on a work sheet in themachine in any position that the platen may assume in its travel, andmeans for supporting said shield on the machine to travel with theplaten and interposed in the line of vision of the operator wheninspecting the written matter on a work sheet carried by the platen,said supporting means including means that enable said shield to beshifted backward from the effective position of use to an unobstructingposition by the operator in reaching back to make an erasure on the worksheet supported on the platen.

2. In a typewriting or like machine, the combination of a platen, atinted transparent shield through which the operator may view thewriting on a work sheet in the machine, and means for supporting saidshield on the machine forwardly of said platen interposed in the line ofvision of the operator when inspecting the written matter on a worksheet carried by the platen, said supporting means including means thatenable the shield to be shifted backward to an unobstructing positionintermediate said supporting means and said platen by the operator inreaching back to make an erasure on the work sheet supported on theplaten.

3. In a typewriting or like machine, the combination of a platen, atinted transparent shield through which the operator may view thewriting on a work sheet in the machine, and means for supporting saidshield on the machine interposed in the line of vision of the operatorwhen inspecting the written matter on a work sheet carried by theplaten, said supporting means including means that enable the shield tobe shifted to an unobstructing position by the operator in reaching backto make an erasure on the work sheet supported on the platen and to beautomatically returned to normal effective position when the operatorshands are withdrawn from the work sheet.

4. In a typewriting or like machine, the combination of a carriage, atinted transparent shield through which the operator may View thewriting on a work sheet carried by the carriage, and means forsupporting said shield on the carriage to travel therewith and in aposition where it is arranged in the line of vision of the operator wheninspecting writing on a work sheet carried by the carriage irrespectiveof the position of the carriage in its line of travel, said supportingmeans including means that enable said shield to be deflected from andto be spring-returned to effective position.
